摘要： An optical system is presented that enables images of a wide range of natural subjects to be well reproduced with their colors, and provides an image pickup system including, at least, an image pickup optical system, an electronic image pickup device having three or more different spectral characteristics to obtain a color image, and a controller for implementing signal processing or image processing on the basis of an output from the electronic image pickup device. The optical element that takes part in determining the focal length in the image pickup system includes an optical element making use of a refraction phenomenon alone. The 400-nm wavelength input/output ratio is 10% or less with respect to an input-output ratio for a 400-nm to 800-nm wavelength at which an output signal strength ratio with respect to an input quantity of light is highest when the input quantity of light is defined by the quantity of a light beam emanating from the same object point and entering the image pickup optical system and the output signal strength is defined by the strength of a signal produced from the controller in response to the light beam.

摘要： A stereomicroscope includes an objective optical system, a variable magnification optical system, and a plurality of imaging optical systems, in which the plurality of imaging optical systems can be moved in a plane perpendicular to the optical axis of the variable magnification optical system. Thus, the stereomicroscope has the advantage that where one of two observers wishes to observe a brighter image, the amount of light can be adjusted, without replacement of a light source, by moving the imaging optical systems.

摘要： A stereomicroscope includes an objective lens for converting light from an object into parallel beams, an imaging lens for forming an image of the object, a prism for erecting the object image, and an eyepiece for observing the object image so that the object image is viewed stereoscopically through the eyepiece, in which the eyepiece is constructed from a single lens system equipped with a variable magnification optical system and an eye lens whose diameter is larger than a viewer's interpupil distance, and optical paths from the object image to the viewer's eyes traverse the positions outside the optical axis of the eyepiece. Thus, the stereomicroscope dispenses with the need for adjustment of the interpupil distance, causes the freedom of the eyepoint to be increased, and allows a viewer to observe the image from any direction whatsoever.

摘要： An image pickup apparatus comprising a first lens unit which comprises at least a negative lens element and at least a positive lens element and has negative refractive power, a second lens unit which has positive refractive power, and an optical path bending reflecting optical element which has a variable reflecting surface disposed in an airspace between a most object side lens component of the first lens unit and a most object side lens component of the second lens unit. This image pickup apparatus changes a magnification by moving the second lens unit along an optical axis and corrects a deviation of an image location by varying a shape of the variable reflecting surface of the reflecting optical element.
